thank you for giving me the location of those. The location of my installation isn't program files, though.
But it appears I was mistaken, when I said that some of the user sets were included in game folder/sets. I saw one of the files ("4 kids") had a similar name to some of the user sets. So I originally thought some of them were in there but not all. But now it makes more sense - *all* the user sets are in appdata :)
